Definitions

  • the present invention refers to a sport shoe fitted with studs particularly suitable for use on artificial turf.
  • Artificial turf has a series of advantages but at the same time has technical characteristics which are different from those of natural turf.
  • Artificial turf usually consists of a dense cover of polymeric fibres of a defined length on which a filler material consisting of sand or rubber of specified granulometry is distributed. ⁇ .
  • Natural grass turf also changes some of the factors linked to shoe grip, stud penetration and friction with the ground surface. Natural grass turf is anchored to the ground by its roots forming a solid mat which at the same time remains elastic and flexible.
  • the traditional stud sinks into the ground moves turf and roots and develops the friction needed to maintain stability; the deformability of the natural turf prevents the stud from being rigidly fixed to the point of penetration and therefore permits the shoe to maintain a small but fundamental capacity to slide or travel at the moment when the foot hits the ground.
  • This sliding action is; useful to the shoe wearer in that it prevents too direct an impact with the ground which could cause trauma to the wearer's joints.
  • the polymeric fibres are immovably anchored to the ground making the playing surface much more rigid and without the levels of horizontal deformation characteristic of a natural grass pitch covering.
  • the studs described do not provide an interaction with artificial turf which is comparable to that of natural turf.
  • the aim of the present invention is to provide a sport shoe particularly for artificial turf designed to reduce shocks to the wearer while maintaining good stability for the foot even on turf made from polymeric fibre.
  • a further aim of the present invention is to provide a sport shoe which has a side penetration coefficient on artificial turf which is comparable to that for shoes suitable for use on natural, vegetable turf.
  • a further aim of the present invention is to provide a sport shoe particularly for artificial turf which overcomes the shortcomings of the known type as mentioned above and providing a simple, rational, easy-to-use and efficient solution at a low cost.
  • the aims described above are fulfilled by the present sport shoe particularly for artificial turf characterised in that it comprises a sole and at least one stud which can be attached to the sole and which has a bottom face resting on the ground and with at least one hollow made in this bottom face.
  • FIG. 2 is an axonometric view from below of an alternative embodiment of the sole of the shoe according to the present invention.
  • FIG. 3 is an axonometric view of a first embodiment of a stud of the shoe according to the present invention.
  • Figure 4 is an axonometric view from below of the stud shown in Figure 3.
  • FIG. 5 is an axonometric view of a second embodiment of a stud of the shoe according to the present invention.
  • FIG. 6 is an axonometric view from below of the stud shown in Figure
  • FIG. 7 is an axonometric view of a third embodiment of a stud of the shoe according to the present invention
  • Figure 8 is an axonometric view from below of the stud shown in Figure 7.
  • the reference numeral 1 indicates as a whole a sport shoe particularly for artificial turf.
  • the shoe 1 is fitted with a plurality of first studs 2 projecting from the sole
  • the front zone of the shoe 1 comprises the toe of the shoe while the rear zone comprises the heel.
  • the first studs 2 have a bottom face 4 for resting on the ground which is designed for making contact with the pitch surface.
  • the bottom face 4 of the studs 2 has a hollow 5 with an elongated shape; the hollow 5 extends in a substantially crossways direction with respect to the longitudinal centre line A of the sole 3 and is designed to aid the drainage of the granular filler material used in artificial turf pitches.
  • the longitudinal centre line A is a line which runs along the shoe 1 from the toe to the heel thereby cutting the sole 3 into two substantially equivalent portions.
  • the first studs 2 are advantageously shaped so that they have at least one pointed portion 6, arrow or wedge shaped, which can be made in different ways.
  • first istud 2 shaped like a truncated pyramid with three side faces as shown in Figure 3, the pointed portion 6 coincides with one of the side edges of the first stud 2. > .
  • first studs 2 have more than three side faces and the pointed portion 6 is defined by the zone intersecting two of these faces.
  • the pointed portion 6 comprises two converging sides of the bottom face 4 of the first studs 2.
  • the first studs 2 have slightly rounded edges but there is however no reason why the edges of the first studs 2 could not have more sharply defined edges.
  • first studs 2 could not have side edges, that is, the surfaces between the bottom face 4 and the sole 3, which are substantially curved and therefore without sharp edges or surfaces which are partly curved and partly flat.
  • the first studs 2 are positioned substantially close to the outer edge of the sole 3.
  • the pointed portion 6 of the first studs 2 points outwards and in particular towards a point on the outer edge of the sole 3 positioned close to the first studs 2.
  • the positioning of the first studs 2 in the edge areas of the sole 3 permits the shoe to improve its coefficient of penetration into the artificial turf at the moment when the foot impacts the ground and thus renders the wearer's movements less likely to cause shocks.
  • the improved penetration on artificial turf obtained with the first studs 2 as illustrated in the figures means that the connection of the first stud 2 with its support point is not excessively rigid and thereby improves the wearer's sense of comfort and safety.
  • the hollow 5 is located on the bottom face 4 of the first studs 2 so that one of its ends is positioned at the pointed portion 6 and therefore faces towards the outer edge of the sole 3 nearby.
  • the hollow 5 forms the axis of symmetry of the first studs 2 thus defining the two portions comprising the bottom face 4.
  • the side edges 7 of the hollow 5 can be curvilinear, as illustrated in Figures 1 to 4, or parallel, straight ⁇ ines, as illustrated in Figures 5 and 6, or convergent straight lines as shown in Figures 7 and 8.
  • the curvilinear side edges 7 have .the concave parts facing opposite directions to define a narrowing close to the centre line area of the hollow 5.
  • the hollow 5 can be shaped in various ways to match different playing fields and climate conditions; for example, the hollow 5 of the first stud 2 in Figure 5 has a bow-shaped cross section while the hollow 5 of the first stud in Figure 7 has a triangular cross section.
  • the hollow 5 of the studs in Figures 3 and 7 has a variable depth which increases as it extends from the pointed portion 6 towards the longitudinal centre line A.
  • the hollow 5 is less deep close to the outer edge of the sole 3.
  • the hollows 5 of the first studs 2 are all parallel to each other and point towards the outer side edges of the sole.
  • the sole 3 shown in Figure 2 has the first studs 2 with the hollows distributed at right angles to the outer edge of the sole 3.
  • this characteristic means that in the toe and heel zones the channels are positioned in a manner similar to that of a sunburst radiating out from an approximately central point in the first front zone (for the front first studs 2) or from the second back £one (for the back first studs 2).
  • the special shape of 'the first studs 2 and their distribution are designed to improve the response of the shoe 1 with the sole 3 so that the pointed portion 6 facing towards the outside of the sole 3 facilitates the penetration and sliding during, for example, a change of direction, while the hollow 5 drains the filler material such as sand or rubber grit along a direction parallel to the stress.
  • Draining the filling material has the effect of providing the wearer with an improved sensation of control over the foot resting on the ground and a perception of stability combined with flexibility which is characteristic of playing surfaces covered in natural turf; this, effect added to the effects described previously make the shoe 1 according to the present invention an item of sports equipment which is innovative and provides higher performance.
  • the sole 3 of the shoe 1 also has a plurality of second studs 8 distally positioned away from the outer edge of the sole 3 and therefore being distributed particularly in the central portions of the first zone and the second zone.
  • the second studs 8 can be of the same type as the first studs 2 or can be of the traditional type; the primary function of the second studs 8 is to provide support while the function of improving penetration and grip is performed by the first studs 2.
  • the second studs 8 are also of a smaller size than the first studs 2.
  • the layout of the studs 2 and 8 can be varied to match the type of playing field, the weather conditions and the type of sport being practiced.
  • the shoe 1 can have a limited number of first studs 2 and second studs 8 as illustrated in the preferred embodiment in Figure 1, or could have a larger number of studs 2 and 8 of a smaller size as illustrated in the alternative embodiment in Figure 2.
  • the shoe 1 can also be fitted with the various types of first stud 2 as shown in Figures 3, 5 and 7 or with other equivalent types.
  • the shoe 1 is designed for use on artificial turf and is particularly useful for other types of pitch covered with hard material and used to practice sports such as soccer, six-a-side football, golf, baseball, American football and rugby.
  • the present invention as described above fulfils the aims proposed and it is emphasised that the shoe, according to the present invention is particularly indicated for all those sports practiced on artificial turf and on hard ground where wearers need to reduce the intensity of shocks resulting from the hardness of the playing surface to which '.wearers are continuously exposed during physical activity.
  • the shoe according to the present invention does in effect improve the side penetration coefficient of the studs on the sole and maintains optimum grip with the ground transmitting to the wearer a sensation of comfort, stability and safety.
  • the hollows made in the bottom face of the studs further improve the performance of the shoes by allowing the drainage of the filler material used on artificial turf pitches and also allowing mud and debris of various types to drain off.
